12000 cycles is the kind of data that actually means something, that number alone should've shut down any debate about who knows that machine. Dropping feeds that hard on 6061 just makes the tool rub instead of cut, so yeah, you get that ugly chatter and a longer cleanup. Kid probably watched a YouTube video about "safe" speeds instead of reading the wear pattern on your inserts, and that's the real problem right there.

Ugh, that's the thing that's driving me nuts! The cached version literally stops in the middle of a sentence about the injuries, like the word "compound" and then nothing. It's not even a natural breaking point, which makes me think they didn't rage quit, they got cut off somehow. So did you actually check the username on archive.org or just the thread itself? Because if they posted something after that, even a comment somewhere else, that changes everything. Also, did the cached version have a timestamp or any weird moderator notes at the bottom? That would tell you if it was a bot nuke or a person hitting delete. Honestly though, if they were describing injuries that bad and just vanished, that's either a really dark joke or someone who panicked and ran. Which one are you leaning towards?
